In this week’s episode, Anna and Guillermo chat with Yaz Khoury and Ismail Khoffi from Celestia. They share how the team prepared for the launch of the Celestia mainnet and what has been happening at Celestia since. They revisit the topic of DA (Data Availability) and explore how rollups and dApp developers can already use the Celestia DA layer. The group discusses Blobstream, which brings the benefits of Celestia to Ethereum and helps to scale the network, as well as community building, the modular thesis and much more.

In this week’s episode, Anna and Guillermo catch up with Justin Thaler, Associate Professor at Georgetown and Research Partner at a16z. 

The group dive into a handful of points from Justin’s ‘17 Misconceptions about SNARKs’ article, discussing if his views have changed since it was published back in 2023 and whether some points have become common knowledge since the article first rippled through the ZK community. They then dive into his new zkVM Jolt, which was initially described along with Lasso in 2023, but has now been implemented and is open to contributions from the community.

Episode 322: Definitions, Security and Sumcheck in ZK Systems with Justin Thaler

In this week’s episode, Anna and Kobi chat with Gal Arnon, Ph.D student from the Weizmann Institute of Science & Giacomo Fenzi, Ph.D. student in the COMPSEC Lab at EPFL. 

Gal and Giacomo are amongst the co-authors of ‘STIR: Reed–Solomon Proximity Testing with Fewer Queries’ and in this conversation, they discuss how their research led them to work on these topics and where the thesis for this particular work sparked from. They set the stage by exploring the history of FRI and discussing some hidden nuances in how FRI works. And then they introduce STIR, a system that can be used in place of FRI, which incorporates various optimisations to improve the performance.

In this week’s episode, Anna and Brendan Farmer catch up with Ben Fisch, CEO of Espresso Systems. They explore the inner workings of the current L2 sequencing landscape and then discuss how a shared sequencing marketplace like Espresso works. They touch on how MEV plays a part in the new system, how the role of the sequencer can be separated into subroles, how all these parts will work together in such a system and much more.

Episode 320: A Deep Dive into Shared Sequencers with Espresso's Ben Fisch

In this week’s episode, Anna catches up with Jordi Baylina, OG Ethereum contributor and Polygon zkEVM Technical Lead. They cover what Jordi has been working on since he was last on the show in 2021. Back then, zkEVMs were still just an idea. Now that many of these systems have launched, they have a chance to look at how these fit into the general L2 landscape. 

They cover Jordi’s view on engineering decentralized systems and how these are rolled out, and the recent research from Polygon, including their AggLayer proposal. They wrap up on what inspires him to keep contributing in the space.
